"Hi,
As planned, I come back after my mile test. I did it 20'' faster than previous test (thanks to the cool impossible) in 7'35'' with a power of 313w.
After two weeks, I find power datas usefull and I'm willing…"

"I should have mentioned: To get this accuracy advantage, you'll need to set your watch to always use the Stryd for pace and distance, and not all watches support that. (The Garmin Fenix 3 does.)
More info:…"

"Even if you live in a flat area without hills, the Stryd has a benefit in providing improved accuracy for pace and distance vs. GPS:
I did a comparison of Stryd vs. GPS earlier in the year, using a surveyor’s wheel as a control…"

"I will be doing more videos on watts and training plans, which I think will be more effective than a new book!
But YES, if you have The Cool Impossible, use the One Mile test chart to design your watts - using the avg watts for your one miler.
If…"

"Great question Fabrice. I think watts are extremely useful for assigning effort on trails. I have coached with power for years in cycling and I use power in coaching many of my ultra athletes. I will be making more watt/power driven…"

"OK, this looks good and consistent. And, your speed meshes great between the two tests.
Lets use these zones below. BUT quick question, do you use a chest strap or rely on a wrist monitoring HR?
HR Zone 1: 0-113
Zone 2: 114-124

I would rate my effort scale at 9. Maybe I could have run a little bit faster but without being sure to finish the 20 minutes
I covered 2.4 miles in this 20 minutes and with an average HR of 147
1 mile test :…"

"Hi Fabrice - Everyone's HR is different and I think we can come up with a plan.
On a effort scale of 1 - 10 (ten being very hard), how would you rate this test from an effort stand point?
Do you know approx how much distance you covered in…"
